UNITED STATES WILLIAM H. BAKER, OF NEWTON, KANSAS.

CALENDAR.

Application filed March 20, 1922. Serial No. 545,219.

To all whom it may concern:

Be it known that I, W ILLIAM H. BAKER, a citizen of the United States, and a resident of Newton, in the county of Harvey and State of Kansas, have invented a new and useful Improvement in Calendars, of which the following is a full, clear, and exact description.

My invention relates to improvements in calendars, and it consists in the combina tions, constructions, and arrangements herein described and claimed. v

An object of my invention isto provide a calendar which may be used for a period of twelve years or more.

A further object of my invention is to provide a device of the character described in which the current year, the name of the month, and the number of days in the month, are brought to view.

A further object of my invention is to provide a device of the character described in which a novel means is employed for bringing the various days and years into registration with an opening, so that the desired month and year may be viewed.

A further object of my invention is to provide a device of the character described in which the parts may be readily renewed so that the calendar may be used for an unlimited length of time.

A further object of my invention is to provide a device of the character described which is simple in construction, which consists of relatively few parts, and which is not likely to easily get out of order.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

invention isillustrated in the accompanying drawings, forming part of this application, in which Fig. 1 is a front elevation of the device, portions thereof being broken away,

Fig. 2 is a side elevation of the device,

Fig. 3 is a rear elevation of the device, and

Fig. 4C- is an'enlarged' sectional view of a portion of the device.

In carrying out my invention, I provide a board 1, preferably made from cardboard and which may be of any shape desired, the form illustrated in the drawings being rectangular; The board 1 has an opening 2 for a purpose hereafter described.

In the drawings, I show a plurality of disks 6, 7, and 8, which are concentrically mounted about a central axis. In Fig. 4., I have shown the disk 6 as being rigidly secured to an eyelet or sleeve 3 which in turn is rotatably mounted on the sleeve 3. The

outer ends of the sleeves 3, 10, and 11 are stepped and carry actuating handles 12, 13, and 1a, respectively. From this construction, it will be apparent that by merely rotating the handles 12, 13, or 14, the disks 6, 7, or 8 may be rotated to the desired position. To lessen the friction between the disks 6, 7,-and 8, I disposed rings or washers therebetween. A washer '15 is disposed between the disks 6 and 7, and a washer 16 is disposed between the disks 7 and 8. In like manner, the disk 6 and the board 1 are spaced from each other by means of a washer 17. The shaftj9 is rigidly secured to the board 1 by means of plates 5 which bear against both sides of the board 1.

The disk 8 isthe largest of the three disks, the disk 7 being next in size, and the disk 6 the smallest, the disks carrying indicator arms 30, 31, and 32, respectively. Printed on the disk 8 is a plurality of calendars 18. These calendars are so numberedas to have the first day of the month they} represent fall on one of the seven days of the week. For example, the calendar 1 has its first dayof the month fall on Monday; the calendar 2 has its first day fall on Tuesday; the calendar 3 has its first day fall on Wednesday, etc. The periphery of the disk 7 lies adjacent to the tops of the monthly calendars 18, and is provided with a ring 19 having thirteen segments 20 therein, twelve of these segments having one month of the year printed thereon withl the number of days in that month. It will be noted that the month Feb. has 28*291) printed thereon (see Fig. 1). The disk 6 has its outer periphery disposed adjacent to the inner side of the ring 19. This disk has a ring-21 which is composed of aplurality of segments 22, these segments having the number of a year printed thereon. One of the segments 22 is a blank for a purpose hereafter described. In the present instance, I have shown the years ranging from 1922 to 1933. The segments 22, having leap years therein, are provided with stars.

The opening 3 is so designed that one segment of the ring 21., one segment of the ring 19, and one calendar month of the disk 8 a e viewed at a single time. the calendar has been arranged so as to show the month of lvlay for the year 1925. It is obvious that by merely rotating the handles 12. 3, and 141-, the calendar may be set for any month in the years rangin from 1922 to 1933. i

in Fig. 5, l have shown the rear of the board 1 as being provided with a sheet of paper 2 3 which has a plurality o't columns thereon. it will be observed that this sheet of paper is divided into twelve vertical rows 2% which have the months from January to December imprinted thereon, and with six horizontal rows 25 which have the years from 1922 to 1938 imprinted thereon. The squares formed by the rows 2 1 and 25 have numbers ranging from one to seven imprinted thereon. It will also benoted that the calendar months 18 on the disk 8 have numbers from one to seven imprinted thereon, these numbers being enclosed in circles. The lower portion of the sheet .28 has the leap years imprinted thereon, these years requiring February to have twenty-nine days.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Assume that the calendar is to be set for the month of April, 1922. It will be noted that on the back of the board 1 (see 3) there is disposed a ring 33 which is concentric with the disk 8. This ring has the names of the twelve months written therein in predetermined places so that when the arm 31 is brought into registration with one of the months, this month is in registration with the opening 2. The ring also has seven numbers therein which designate the places to which the arm 30 is to be swung so as to bring the desired calendar into. registration with the opening 2. The ring further has year numbers thereof for the arm 32. The row 24-, which has the word April imprinted on the top thereof, and the row 25. which has the year 1922- impi'inted there on. are taken, and a line is drawn down these two rows. Where these two lines meet, the number of the required month is to be found. In this case,it will be noted that the number is 6 and that therefore the disk 8 has to be rotates so as to bring the month 18 on the disk 8 having the number 6 thereon into registration with the opening 3. The operator knows that the calendar 18, having the number 6 thereon, is in registration with the opening 2 when the arm 30 registers with the number 6 on the ring 33,, The wheel 13 is now rota-ted so as to In Fig. 1,.

. d ays therein.

bring the name April into registration with the opening 3. It will be obvious that the arm 31 tells the operator when April served that the calendar now ready for use during the entire month of April. It will also be observed. that these three opera tions can be made from the back of the calendar. It will further be observed in Fig. ii that all of the months 18 have thirty-one low, whereby the user of the calendar knows the number of days in that month. When a leap year having a star thereon is used, the month of February also having a star thereon tells the operator that February has twenty-nine days in the month thisyear instead of twenty-eight days. I

The calendar may be used as an advertising medium if desired, since pictures, printed matter, or the like, may be disposed on the front of the board, sons to be readily viewed exteriorly of the calendar. The board 1 carries an eyelet 26, and a supporting bar 2?. which is pivotally secured to the board at 28. The board 1 can bedisposed on a table, the bar 27 keeping the board in an upright posit-ion. It will be observed that the calendar can be renewed for an indefinite length of time by merely providing new disks 6 and printed paper 23.

.drom the foregoing it will be observed that I have provided a simple calendar which may be used for a great number of years by merely changing two of the parts thereof. The device may be' used as an advertising mediuu'i if desired. As heretofore stated. the device is simple in construction and is efficient for the purpose intended. The blank segn'ients in the rings lfl'and 21 are to n'event the arms 31 and 32 from appearing in the opening 2.

I claim:

1. A device of the typedeseribed com- It is obvious, however, that endars thereon with thirty-one days in each calendar, each calendar having the first of the month starting on a different day, and a handle operatively connected to each of said disks, whereby said disks can be rotated by said handles to bring any one of said calendars, names of months, and numbers of years into registration with said opening.

2. A device of the type described comprising a board having an opening therein, three disks of different sizes rotatably and concentrically mounted on said board, the smallest disk being disposed adjacent to the opening and having numbers of years printed thereon, the next largest disk having the names of the months and the number of days in the month imprinted thereon, and the largest disk having seven monthly calendars thereon with thirtyone days in eacli calendar, each calendar having the first of the month starting on a difi'erent day, and having a key number thereon, and a handle operatively connected to each of said disks, whereby said disks can be rotated by said handles to bring any one of said calendars, names of months, and numbers of years into registration with said opening, and said casing having a guide chart thereon, said chart having twelve rows with a name ofmonth at the top of each row, and a plurality of rows intersecting said first named rows at right angles, each of said second named rows having a number of the right calendar to use for the respective month and year the rows of which this key number is in.
